You could import and convert styles from other keyboards, at least you could Roland styles. 
However it is the only brand on which I ever had to worry about breaking keys.  They were not that strong.  I remember replacing several.
My friend DickieT bought a KN800 because I had one at the time.  He left it in the trunk of his car and the plastic case melted.  It still worked but it was really ugly. 

I had 800, 1000, 2000, and 5000.  I sold the 5000 to DNJ.  Still selling him stuff.
